Road vehicle having an ambient air purification device, ambient air purification device and filter element

An ambient air purification device for a road vehicle, the road vehicle comprising a vehicle frame and a rear axle connected to the vehicle frame, wherein:

• the ambient air purification device comprises one or more filter elements;
• the ambient air purification device is configured to remove dust, particulate matter, and/or gases from ambient air;
• the ambient air purification device is configured to be arranged transverse to a longitudinal vehicle axis in an exterior region of the road vehicle in an underfloor region at a vehicle rear of the road vehicle such that at least the one or more filter elements in a mounted state at the road vehicle are arranged in the exterior region and behind the rear axle of the road vehicle in a travel direction of the road vehicle;
• and
• the ambient air purification device is configured to be received in an installation space of the vehicle frame so that the ambient air purification device is flowed through in a longitudinal vehicle direction and a free outflow zone of the ambient air purification device is arranged in the exterior region and behind the ambient air purification device in the travel direction of the road vehicle.
